Two cases of meningitis due to group B streptococci are reported. One
of them developed during post partum, the other in a patient with cirr
hosis and ascitic decompensation. The few cases of streptococcal menin
gitis reported so far in literature were reviewed. The main settings i
n which they develop were established: post partum, elderly people, im
munocompromised patients. Antibiotherapy with betalactams, and especia
lly penicillin G, is the reference treatment.
